The Honda 31105-PZ1-003 Brush Holder Assembly is a genuine OEM component designed for BF115, BF130, BF135, BF140, and BF150 outboard motors. As a direct Honda OEM replacement, this assembly is manufactured to the same specifications as the original unit installed at the factory, ensuring a proper fit within the charging system of these four-stroke outboards. Confirm your motor's serial number against the fitment table before ordering, as Honda supersedes parts at production breaks and more than one assembly variant may exist across the model range.
Key Features
- Genuine OEM Charging System Quality — manufactured by Honda to the same specification as the original, maintaining correct brush contact pressure and electrical continuity within the alternator assembly
- Direct OEM Replacement — designed to drop into the alternator housing of BF115, BF130, BF135, BF140, and BF150 outboard motors without modification
- Wide Outboard Fitment — covers Honda's mid- to high-horsepower four-stroke outboard range, including the BF115, BF130, BF135, BF140, and BF150
- Serial Number Verification Recommended — Honda updates parts at serial number breaks, so cross-reference your motor's serial number with the compatibility table to confirm this is the correct assembly for your unit
- Charging System Integrity — worn or damaged brushes cause erratic or failed battery charging; replacing this assembly restores consistent alternator output and keeps onboard electronics properly powered
The Brush Holder Assembly houses the carbon brushes that maintain a sliding electrical contact against the rotor slip rings inside the outboard's alternator. As the rotor spins, these brushes carry current into the rotor field winding, allowing the alternator to generate the charging voltage that keeps the battery topped up and the motor's electrical systems running. When the brushes wear down or the holder cracks, brush contact becomes intermittent or fails entirely, leading to a dead battery, erratic instrumentation, or a motor that won't start — symptoms that are quickly resolved by fitting a fresh assembly.
